IMPORTANT SAFETY INFORMATION

An under-rated or worn rope may break and whip

violently. Use a polyester or polyester-jacketed rope

with a breaking strength of 16,000 pounds.

Failure to observe this warning could result in severe

injury or death.

• Check the condition of the entire rope before use.

A worn or damaged rope can break under tension

and whip violently.

• Do not maintain a stationary rope on a rotating

capstan. The wear generated may cause the rope

to break under tension and whip violently.

Failure to observe these warnings could result in

severe injury or death.

Attach the pulling rope to the cable with appropriate

types of connectors. Select connectors with a rated

capacity of 4000 pounds. An under-rated connector

can break under tension.

Failure to observe this warning could result in severe

injury or death.

Do not put ngers through holes in

elbow unit. Rotating parts may cut off

ngers.

Failure to observe this warning could

result in severe injury or death.

Keep hands away from the capstan.

Rope at the capstan can crush a hand.

Failure to observe this warning could

result in severe injury or death.

Do not wrap rope around hands,

arms, waist or other body parts.

Do not stand in spent coils or tailed

rope. Hold rope so that it can be

released quickly.

Failure to observe this warning could

result in severe injury or death.

Rope, cable, or a connecting device can break under

tension, causing the rope to whip violently.

• Do not allow any unnecessary personnel to remain

in the area during the pull.

• Do not allow any personnel to stand in line with the

pulling rope.

Failure to observe these warnings could result in

serious injury or death.

IMPORTANT SAFETY INFORMATION

Do not allow the rope to overlap on the capstan.

If the rope approaches the top of the angled part of

the capstan, relax the tailing force. If an overlap does

occur, shut off the puller immediately.

Failure to observe this warning could result in severe

injury or death.

Use this tool for manufacturer’s intended purpose

only. Do not use the cable puller as a hoist or winch.

• The cable puller cannot lower a load.

• The load may fall.

Initial Assembly

1. Insert the leg and wheel assembly tubes together

and secure with a short detent pin.

2. Lock the leg from pivoting by inserting the long

detent pin into one of the holes in the puller head

side plate.

3. Lay the puller down so the bar with the small

sheave is next to the ground and the main boom

is up in the air.

4. Slide the telescopic boom into the main boom and

secure with a long detent pin.

5. Slide the nose onto the telescopic boom and secure

with a long detent pin.

Assembly

To open from the folded position shown in Fig. 1, pull

the detent pin that locks the leg to the puller head and

let the wheel assembly drop to the oor as shown in

Fig. 2. Pull the pin that locks the wheels to the leg and

rotate the wheels as shown in Fig. 2. Replace the pin

that locks the wheels.

Lift up the puller head until you can insert the detent pin

in one of the four positioning holes as shown in Fig. 3.

The bottom hole shown often works well as it allows the

puller head to act as a counterbalance for easy trans-

port and conduit attachment.

Pivoting the nose unit:

The nose unit pivots and locks at various degrees of

rotation. It is locked in place by a detent pin set located

between the sheave and the end of the boom tube

receptacle. To pivot, squeeze the grips on the detent

pins fully inward.

Squeeze

Grips

Make sure the detent pins on both sides are fully

retracted before trying to pivot. Release the grips when

the desired pivot angle is reached, and pivot slightly

more to allow both detents to engage in the closest

holes.

When the detent pins are squeezed to the fully inward

position, they can be locked in place by twisting them

counterclockwise.

Twist to lock.

Never pull cable with the detent pins locked inward; the

nose unit must be locked from pivoting before pulling.

Adjust the puller head to the bottom of the two puller

head pivot positions.

Adjust telescopic boom so that it is long enough to

reach the conduit or pull out the desired cable tail.

Reinsert the detent pin.

Place the conduit attachment nose near the conduit.

Setup—Up Pull

UT4 and UT4-22 Cable Pulling Systems

Greenlee / A Textron Company 4455 Boeing Dr. • Rockford, IL 61109-2988 USA • 815-397-7070

Setup—Up Pull (cont’d)

If the conduit is free-standing or without threads, posi-

tion the clamping jaws so that the conduit will butt up

against the overhanging ats of the grips.

Tighten the knurled knob until the locking jaws are tight

against the conduit at all four grip points.

Locking

Pull the pivot locking pin and adjust the nose angle so

that it is in line with the conduit.

Unscrew the knurled nut until the clamping jaws can t

around the conduit. The jaws will t 2" to 4" conduit.

Butt the bottom of the clamping jaws up against the

conduit lock nut, or the lip of the grips against the top of

the conduit.
